【Abstract】 WT5BZ]Ultrafine Sb 2O 3 powders were prepared by ball mill methods; the characteristics of the composite powder was studied by TG,DSC and laser scattering methods The results show that the beginning temperature of kaolin structure variation becomes low; the beginning temperature of kaolin structure variation is also changed with the quantity of Sb 2O 3 in the composite powder The chemical combination reaction of Sb 2O 3 and kaolin is proceeded at a narrow range of temperature. To Sb 2O 3,when the quantity of kaolin in the composite powder is large, the active energy E of the chemical combination reaction becomes small, the frequency factor A value becomes large, and the composite reaction is 0 grade reaction更多还原
